Struct aws_sdk_dynamodb::types::builders::KeySchemaElementBuilder

#[non_exhaustive]
pub struct KeySchemaElementBuilder { /* private fields */ }

A builder for KeySchemaElement.

Implementations

impl KeySchemaElementBuilder

pub fn attribute_name(self, input: impl Into<String>) -> Self

The name of a key attribute.

This field is required.

pub fn set_attribute_name(self, input: Option<String>) -> Self

The name of a key attribute.

pub fn get_attribute_name(&self) -> &Option<String>

The name of a key attribute.

pub fn key_type(self, input: KeyType) -> Self

The role that this key attribute will assume:

• HASH - partition key

• RANGE - sort key

The partition key of an item is also known as its hash attribute. The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

The sort key of an item is also known as its range attribute. The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

This field is required.

pub fn set_key_type(self, input: Option<KeyType>) -> Self

The role that this key attribute will assume:

• HASH - partition key

• RANGE - sort key

The partition key of an item is also known as its hash attribute. The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

• HASH - partition key

• RANGE - sort key

pub fn build(self) -> Result<KeySchemaElement, BuildError>

Consumes the builder and constructs a KeySchemaElement. This method will fail if any of the following fields are not set:

• attribute_name
• key_type

Trait Implementations

impl Clone for KeySchemaElementBuilder

fn clone(&self) -> KeySchemaElementBuilder

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KeySchemaElementBuilder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for KeySchemaElementBuilder

fn default() -> KeySchemaElementBuilder

Returns the “default value” for a type.

impl PartialEq for KeySchemaElementBuilder

fn eq(&self, other: &KeySchemaElementBuilder) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
